According to the allegro docs, when I use the allegro key callback, the
function is in this form:

  int keyboard_callback(int key) {}

What format does the "key" argument come in?  I tried a simple program to
print the key argument and it crashed due to sigsegv.

    Here is my program:

    int jgKeyCallback(int key);

    int main(void) {
     allegro_init();
     install_keyboard();
     keyboard_callback = jgKeyCallback;
     while(!key[KEY_ESC]);
     allegro_exit();
     return 0;
    }

    int jgKeyCallback(int key) {
     cout << key;
     return key;
    }

Can someone tell me how to process this correctly?  It'd be nice to be able
to detect the insert key and then be able to keep it globally for
insert/overwrite switching and stuff.

I don't think it's a scancode becuase I tried using that and it didn't work,
so I'm at a loss.

Thanks!
